It is designed for Class 30 protection, meaning it can handle a locked-rotor current of 13 times the set current (13 x I_in) without nuisance tripping during motor start, while still providing overload and short-circuit protection. This makes it suitable for heavy-starting loads like conveyors, crushers, and large fans where the start-up time exceeds standard Class 10 or 20 curves.
